IPC: C04B2/10
Filed: 1917-11-26
Abstract: 111,853. Kennedy, H. A. Nov. 28, 1916, [Convention date]. Refractory substances containing lime and magnesia.-A refractory material for furnace linings &c. is made by clinkering, at a temperature higher than that employed in the manufacture of Portland cement, a finely divided and intimate mixture containing approximately 78-92 parts of CaO and MgO, 2-13 parts of SiO2 and alumina or iron oxide or both. To a certain extent, alumina and iron oxide may be replaced by silica or in their place basic slag, blast furnace slag, bauxite, chrome iron ore, &c. may be employed. Magnesian limestone or dolomite is preferred as the source of CaO and MgO. The limestone may be first calcined and hydrated and the materials may be mixed wet or dry. The heating is preferably effected in a rotary kiln by means of a powdered fuel flame, the kiln being inclined less or rotated more slowly than a cement kiln so that the period of burning will be greater. The product is finally cooled in a cooling-cylinder and is then ready for use.

In a process for recovering ammonia from a gas mixture by conversion to ammonium sulphate: (i) the gas mixture is washed with water and divided into 2 streams; (ii) the first stream is neutralized in a washer by a solution containing ammonium sulphate and sulphuric acid, the concentration of ammonium sulphate being such that little or no crystallization occurs; (iii) the second stream is neutralized in an immersion saturator by an ammonium sulphate/ sulphuric acid solution discharged from the washer, (iv) the ammonium sulphate concentration in the immersion saturator is adjusted to grow ammonium sulphate crystals in the saturator and (v) the crystals are collected. The process is applicable to off-gases from acrylonitrile production and comprising -ammonia, nitrogen, oxygen, propylene, propane, acrylonitrile, hydrocyanic acid, acetonitrile and catalyst dust. In one embodiment, gases from reactor 1 are cooled-to 70-300 C. at 2 and fed to jet washer 3 to remove polymers and catalyst dust. Cooling water is injected if the gas temperature is above 150 C., and a mixture of cooling water and wash water may be recycled at 15. Washed gas is passed through droplet separator 13, preferably after injection of fresh or waste water from elsewhere in the installation. Gas stream A is then passed through washer 5B (which may be a jet washer, immersion washer or washing column) where it is treated in parallel flow with ammonium sulphate solution containing 3-5 wt. per cent H 2 SO 4 . 100-300 m.<SP>3</SP>/hr. are stated to remove 100-500 kg./hr. of ammonia from about 50,000 Nm.<SP>3</SP> of gas mixture. A droplet separator is,provided at 14. Sulphuric acid is added to the solution in 5B to maintain the required concentration. 'The solution may be just undersaturated with ammonium sulphate or oversaturated to a salt content of, e.g. 20% by volume. The sulphate solution is fed via pipe 29, circulation vessel 8, heat-exchanger 9 and pipe 32 to immersion saturator 5A to treat gas stream A. Water is evaporated in 5A to yield a crystal-containing sludge which is centrifuged at 6. The mother liquor is returned either to 5A or 5B. Gas from droplet separator 7 is fed via 27 to droplet separator 14. In an example, ammonium sulphate having the following grain sizes is produced: up to 0À2 mm., 3%; 0À2-0À5 mm., 12%; 0À5-1 mm., 64%; 1-2 mm., 21%.
